Problems solved by technology
In order to ensure the accuracy of the test, the measuring head of the deformation testing device should be perpendicular to the plane where the measuring point is located. Measure the deformation of a certain point of the car door panel in the horizontal direction. Many points on the door panel cannot be tested, which makes the deformation data of the car door panel incomplete, which in turn affects the product quality and safety performance of the car door panel.

The invention belongs to the automobile door panel technical field, and discloses a deflection testing device including a rotary mechanism and a measuring head assembly; the rotary mechanism can movein X, Y and Z directions, wherein every two of said 3 directions are mutually vertical to each other, and the rotary mechanism can revolve; the measuring head assembly is arranged on the rotary mechanism, configured to move and rotate to certain point on the automobile door panel, and can measure the deflection of the point in a direction vertical to a surface on which the point is located. The deflection testing device can measure most points on the automobile door panel, and can obtain more complete and full deflection data of the automobile door panel, thus improving the automobile door panel production quality and safety performance.
Description
technical field [0001] The invention relates to the technical field of automobile door panels, in particular to a deformation testing device. Background technique [0002] The car door panel is an important part of the car door. The car door panel will be subjected to bending force during use. Therefore, after the production of the car door panel is completed, the car door panel needs to be tested to ensure its safety performance. [0003] Usually, the test of the car door panel refers to testing the deformation of a certain point on the car door panel under a certain pressure. In order to ensure the accuracy of the test, the measuring head of the deformation testing device should be perpendicular to the plane where the measuring point is located. The deformation of a certain point of the car door panel is measured in the horizontal direction. Many points on the door panel cannot be tested, which makes the deformation data of the car door panel incomplete, which in turn aff...
